To all whom t may concern;

Be it known that I, EDUARD EHRENBERG, a subject of the German Emperor,residing at Hamburg, in the German Empire, have invented certain new anduseful Improvements in Brushes or Brooms, (toI which I have obtainedLetters Patent in Germany,No. 49,87 3, dated June 9, 1889,) of which thefollowing is a specification.

This invention relates to that class of brushes and brooms which areadapted to deliver jets of water between the knots; and the' object ofthe same is to facilitate the process of washing the fronts ofbuildings, railwaycarriages, and other large surfaces.

In the accompanying drawings, in -which similar letters denote similarparts throughout the several views, Figure l is a side elevation of abrush provided with my invention; Fig. 2, a cross-section; and Fig. 3, alongitudinal section of the same, showing a particular device within thehollowY stock adapted to regulate the discharge of the water, while Fig.4 represents, in a longitudinal sectionof the brush, another positionot' the regulating device, as shown in Fig. 3.

In carrying Iny invention into effect I provide a hollow handle c and ahollow stock a, b, the former being adapted to deliver the water intothe cavity (Z within thelatter,from which it is discharged among,between, and past the knots through a series of holes f, suitably andregularly positioned for the desired purpose. The hollow handle c isprovided with a suitable hose connection to facilitate the supply ofwater. NVithin the hollow space d of the stock ct b I tit a slide orvalve t, adapted to regulate the discharge of the water from the stockin respect both of direction and quantity. This valve g, which isadmitted to slide longitudinally, has perforations gx, corresponding innumber and position with those in the stock, and flexible tubes or studsh, entering the perforations f in the part b of the stock and capablefrom their adjustability by means ot a handle k in point of position todirect the water and regulate the quantity, so that it may be discharged'either in right lines, Fig. 3, between the knots for rinsing ordirected among the bristles, Fig. 4, as for washing.

Havingy fully described my invention, what I claim, and desire to secureby Letters Patent, is-

1. A's an improvement in brushes and brooms, the combination of thehollow stock provided with perforatons between the bristles, the hollowhandle, and the adjustable valve or slide Within the cavity of thestock, having exible tubes or studs entering said perforations,substantially as set forth.
